Usage tips
Word family
The noun 'die Deponie' (landfill) is closely related to the verb 'deponieren' (to deposit/store), which means 'lagern' (to store) or 'hinterlegen' (to deposit). A 'Deponie' is therefore a place where something—in this case trash—is stored permanently.
EXAMPLE
Das Unternehmen muss nachweisen, wo es seine Abfälle deponiert.
The company must prove where it deposits its waste.
Preposition and case
Pay attention to the preposition 'auf' and the case that goes with it. When it is about direction, you use the accusative ('auf die Deponie' — to the landfill). When it is about location, you use the dative ('auf der Deponie' — at/on the landfill).
EXAMPLE
Der Müllwagen fährt den Abfall auf die Deponie.
The garbage truck takes the waste to the landfill.
Official term
'Deponie' (landfill) is the official and technical term for a place where waste is stored. You often find this word in official texts, news reports, or discussions about environmental protection.
EXAMPLE
Die Gemeinde plant die Schließung der alten Deponie.
The municipality is planning to close the old landfill.

Deponie vs Halde
spoil heap / pile
'die Halde' and 'die Deponie' can both refer to places or piles where material is lying. The difference lies in the purpose and the organization. A 'Halde' is usually a piled-up hill of material, for example from mining or industry. A 'Deponie' is a designated and secured place where waste is stored permanently. The words can be confused because colloquially people also say 'Müllhalde' (dump). More precisely, however: for waste and official storage, 'Deponie' fits better; for piled-up industrial or mining material, 'Halde' is more appropriate.
Deponie
Der Bauschutt wird nicht im Wald abgeladen, sondern zur Deponie gebracht.
The construction rubble is not dumped in the forest, but taken to the landfill.
Halde
Neben dem alten Bergwerk wächst eine dunkle Halde aus Steinen und Erde.
Next to the old mine, a dark spoil heap of stones and earth is growing.
